The water enters through the tube 16 into the inlet chamber 7 in thepiston 6 and, passes outthrough the open Valve into the right hand sideof the cylinder, as shown In Fig. 1, closing the exhaust "alveon thatside I and driving the piston to the left. The mo ment the valve stem ofthe inlet valve comes on the head. This inc os' in contact with the head4 of the cylinder, the inlet valve is shifted from its seat 19- and thecup seats itself or almost seats itself l in of the water passing aroundthe seat 0 the inlet valve creates suflicient back pressure to suddenlythrow the valve to. the opposite side. The

aright hand end of the cylinder is therefore pressure is'transferred tothe left "of the cylinder, which pressure in the left cut off from theinrush of wateriland the and end hand end of the cylinder is suflicie'ntto unseat the exhaustvalve and force itto its oppositeside. The exhaustvalve is therefore opened on the; opposite side of the cylinder and thepiston head is driven to the right,

and thus the motor drives the piston back and forth in the cylinder. Inthe oscillating rotatory typeof motor; Where the piston is mounted as awing on the rocking or oscillatory piston rod, the valves are mounted inthe same way to come in contact with the rotatory oscillation of themotor cylinder.
